Missables Guide (Xenoblade Chronicles 2)

So, as we know, Indol quests become completely inaccessible after a certain point during Chapter 8. Since I have not seen anyone else do this yet, I want to go ahead and take the initiative to put every known missable in one place for the completionists such as myself.

This thread will be updated as more people add information, but I have been labbing this for the last day to see what all is missable. I have gotten Indol to 5 stars development, so I believe I have accessed everything avaliable to this area, however there may be quests that im unaware of obtainable outside of Indol that still require you to visit Indol, that become inaccessible.

So, without further or do, here is my current missables list!

(P.S. Having this thread as a sticky would be great btw, even if it is just temporary until we get a comprehensive missables guide on gamefaqs or something)

In order to finish the quest “The Riddle on the Wall”, you need a set of key items. But “Uncover the Truth” takes those key items! And in order to complete “Uncover the Truth”, you need to complete “The Riddle on The Wall”. Credit u/Sec0rs

The Indol wall painting behind the tents in Refugee Campground is moved to Fonsett Village after the Indol event

(Possibly?) MISSABLE ITEMS/SHOPS

EDIT: Apparently the Indol shops are moved to Leftheria!

(Possibly?) MISSABLE UNIQUE NPC CONVERSATIONS

INDOL

I did not record exactly who says what at which level of development, but there are unique npc conversations locked behind EVERY development level, up to level 5. Currently unknown if these conversations are ported to Leftheria after the Indol event.

INDOL MERCENARY MISSIONS – Are they missable?

User u/ZFFM has pointed out that he got every Indol merc mission by default once he was locked out of Indol. These merc mission will be moved to Leftheria, and they DO NOT require you to get all 5 development stars for indol before it is locked.

Throwing money off the the ledge in Indol (Trophy-icon “good deed” apparently needed for Perun)

This is the extent of my list so far. Please let me know if I missed anything guys! As of now the main thing I am worried about is if there are any sidequests outside of indol, that require you to visit indol to finish the quest. Possibly Rare Blade quests that I am unaware of?
